20 Most Recent Whirlpool GH5176XPS Microwave Oven Questions & Answers

In order to determine if your microwave oven is working correctly or not we need to perform a simple test. Fill a glass measuring cup with 1 quart of water, take a temperature reading of the water. Place the water in the microwave & set the timer for 2 minutes & start the unit. After 2 minutes, take a temp reading of the water. You should have a 30 degree temp rise. If you are not getting the correct temp rise, your microwave oven will need the magnetron replaced.

Make sure that the program controller is working if not check power - step down supply, the pads are responding- if not faulty pads- or the door switches, if the switch contact are not good then it will not trigger the processor to switch on the waveguides. If the lights or fan work without any display or action of program being triggered to start then it can be a possible fault on the main board or the processor. Sometimes insect secretion can short the board and display panel and so the processor can work in such an erratic manner. If so clean,solder and reset the board.Now identify the parts by clicking this link: http://www.espares.co.uk/advice/microwave/a/5/141/identifying-microwave-parts.html

If there is no heating please do not switch on unless you have confirmed the fault. It is possible that the Magnetron is faulty, the temperature cut off is faulty or the main capacitor is short. It is also quite possible that insect can get into the oven and create soft spots. When you switch on these will create a short and make the voltage jump and in the long run damage the magnetron.So Remove cover after disconnecting , check for dirt/moisture in the cabin, if so wipe clean and dry, check the magnetron and area clean and use an jet air to clean off. Check the wave guide covers, if food had depositedthen it must be checked or replaced.

Now keeping clear of the microwave, switch on, use a cup of water inside to test. If you notice any sparks shut off as the magnetron or the main HT capacitor can be faulty. replace with same type.If there is heating without any issues, you can use the microwave safely

there is a loose internal connection somewhere. high voltage, circuit board, or door switches.

Hi, Here is a tip that will help you to figure out what is wrong with yourMicrowave Oven....Microwave Oven Basic Troubleshooting Tipsheatman101

The problem is more than likely a bad magnetron, "heats food" the other two considerations are the high voltage capacitor and diode.

It sounds like the magnetron may have either failed or is not being supplied with the extremely high voltage required to run it.
Make sure the !!!!capacitor is discharged!!!!! before attempting any sort of repair.
Check the door interlock switches first then the high voltage diode with either an AVO model 8 on high resistance range for short circuit, the feed fuse on the primary of the high voltage transformer and then finally, the magnetron is best checked by substitution.
Hope that helps.

It is a failure of the front loading latch protect switch which can be short. Normally only when the door latches the circuit is through to the main circuit.
hence a possible leaf switch that could have been stuck on could be the main issue.
Open cover and check at the pointt of the door switch latch.
Hope this helps.

Try sears dept. stores in the hardware

If it is only when he exhaust fan is on, something is in the fan. Remove the grill and investigate. If it is from the Magnatron fan you will have to remove the front panel.
Eric

you need to adjust the door travel adjustment on this micro-switch,if its open and registering open the control board will not let the unit start due to R.F. radiation safety concerns,you should adjust the door and after it starts to operate,have the R.F. leakage at the door checked to make sure your safe and till so don't stand too close till its certified so

the magnatron is on the way out

they are expensive but get a quote

can you give me more information what is it not doing
come back to me

F-7 is the microcomputer board failure code. The board will need to be replaced.

Check contacts to control board first.

If control board is OK then test the high voltage capacitor,the rectifier diode.or the magnetron. If all this are fine, test the control board.

Thediode and capacitors can br tested. The capacitor must bealloweddischarge before testing, or you risk to get electrocuted, evenifpower is off. Capacitors can get discharged by shorting theirtwocontacts.
Before replacing the magnetron test also the control board.
Replace the magnetron if the checks and all of the high voltage component tests are good, but the unit still does not heat.



All locations, and description of this parts can be located using the diagram here: Counter top.

Parts must be tested to find out what is wrong.

Remember that microwaves are potentially dangerous devices if not repaired properly, the job must be done by a competent person.
A microwave energy leakage test must always be performed when the oven is serviced for any reason.

Regarding parts, contact the seller here to purchase parts.

Get the door safety interlock switches tested for continuity and alignment, by a qualified service engineer. If a door switch is not switchimg. there will be no power to the magnetron and no heating.

Question edited for clarity and typos. This is the only one available online. Microwaves are so inherently dangerous inside, Service Manuals are strongly restricted from public access. Make sure his medical and life insurance is up to date. http://www.uncleharrywizard.com/nephewclub/wizardrange/whirlpool-kitchen-aid/8178573-km-30-whirlpool.pdf Have a read. The Triac will be hard soldered to the mainboard or power board, so just look for the one with the same number. https://www.fixya.com/support/r29874712-repairing_microwave_ovens ..

1. Clean the door sensors: If your microwave is showing "DOOR" when you press start, it's possible that the door sensors are dirty or obstructed.Try cleaning them with a soft cloth or cotton swab23.
2. Replace the door switches: If cleaning the door sensors doesn't work, it's possible that one or more of the door switches are faulty and need to be replaced. You can follow this video tutorial to replace the door switches yourself3.

If none of these steps work, it's best to contact a professional or the manufacturer's service center for further assistance. I hope this helps!

The fuse for the Whirlpool microwave model WMH31017HZ07 is located inside the microwave oven. You will need to remove the outer cover of the microwave to access the fuse. Here are the steps to follow:

1. Unplug the microwave from the power source.
2. Remove the screws on the top of the microwave that hold the top grill in place. Remove the grill.
3. Locate the screws that hold the control panel in place. Remove the screws and carefully pull the control panel forward.
4. Locate the fuse holder on the right side of the control panel. Remove the fuse holder by pulling it out.
5. Check the fuse to see if it is blown. If it is, replace it with a new fuse of the same type and rating.
6. Reinstall the fuse holder, control panel, and top grill.
7. Plug the microwave back in and test to see if the light is working.

If the light still does not turn on after replacing the fuse, there may be another issue with the microwave and it may require further troubleshooting or repair.
